Li Ciming (1830-1894) won great renown from his Diary of the Yueman Hall, which contains a million words of critique on the classics, histories, and intellectuals. In awe of and fearing his learnedness, most scholars of later ages traced the origin of his scholarship through the content of his Diary, while others discussed late Qing scholarship based on his comments. These discussions, however, can hardly articulate the ultimate concerns left after Li's critical comments. Through careful analyses of his arguments in the Diary, the present essay observes that Li regarded the scholarship of the Qianlong-Jiaqing era (early 18th to early 19th centuries)as his model and thereby set his criteria for academic criticism. By praising and criticizing scholars and their works, Li aimed to rectify the deviation in scholarship; rebuild the tradition of Han studies, which had long collapsed; and make a return to the exemplary Qianlong-Jiaqing era in both scholarship and politics. This will serve as an example of how traditional scholars endeavored to maintain a fine legacy in scholarship and social customs.
